Solution Overview

Problem

Current treatments for diabetes mellitus, inflammatory bowel disease, non-alcoholic fatty liver disease, and non-alcoholic steatohepatitis are inadequate, with a need for effective pharmaceutical interventions, particularly targeting the interactions between Galectin-3 and insulin receptor or integrins.

Innovation Solution

Development of anti-Galectin-3 antibodies or binding fragments that selectively disrupt the interaction between Galectin-3 and insulin receptor or integrins, administered to subjects to treat these conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current treatments for diabetes mellitus and liver diseases are used, then existing therapeutic options are available, but treatment effectiveness is inadequate

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidtargeting capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent uses anti-Galectin-3 antibodies as intermediary molecules to block the interaction between Galectin-3 and insulin receptor/integrins. The antibody serves as a mediator that binds to Galectin-3 and prevents it from interacting with its target proteins, thereby treating diabetes and liver diseases without directly modifying the target proteins themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If Galectin-3 interaction with insulin receptor is blocked, then insulin resistance is reduced, but new therapeutic mechanism is required

Engineering Contradiction:
Improveinsulin sensitivityVSAvoidtherapeutic mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and neutralizes the harmful interaction between Galectin-3 and insulin receptor by introducing antibodies that specifically bind to Galectin-3. This removes the pathological binding event without requiring modification of the insulin receptor itself, thereby improving insulin sensitivity through a targeted intervention.

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-affected harmful factors

If Galectin-3 interaction with integrins is disrupted, then inflammation is reduced, but selective binding capability is needed

Engineering Contradiction:
Improveinflammation levelVSAvoidbinding selectivity
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent employs antibodies with specific binding characteristics that target Galectin-3 at particular epitopes. The CDR regions of the antibodies are designed to recognize and bind selectively to specific regions on Galectin-3, ensuring localized and selective disruption of the Galectin-3-integrin interaction while minimizing off-target effects.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The antibodies effectively reduce insulin resistance, weight gain, liver steatosis, and inflammation, providing therapeutic benefits for diabetes, inflammatory bowel disease, and liver diseases by disrupting harmful interactions.

Implementation Method 1

contacting an interaction between Gal3 and the insulin receptor or the integrin, or both, with an anti-Gal3 antibody or binding fragment thereof that selectively binds to Gal3 and disrupts the interaction between Gal3 and the insulin receptor or the integrin
